Alumina semiconductor ceramic seal ring
Alumina ceramics
1. High hardness
Rockwell hardness is HRA80-90, the hardness is lower than diamond, far more than the wear resistance of wear-resistant steel and stainless steel.
2. Excellent wear resistance
Measured by professional research institutions, its wear resistance is equivalent to 266 times of manganese steel. Gaoming cast iron 171.5 times, according to our more than ten years of customer tracking survey, under the same working conditions, can extend the service life of the equipment at least ten times more.
3. Light weight
Its density of 3.5g/cm3 is only half that of steel, which can greatly reduce equipment load.
Features:
High mechanical strength
High resistivity and good insulation
Mohs hardness of 9 and excellent wear resistance
High melting points and corrosion resistance
Good stability
Optical properties
Ionic conductivity
Application industry: Machinery, electronic, chemical, petroleum etc.
Specific application: Electrical ceramic substrate, plunger, sealing ring etc.
